100G QSFP28 BIDI SR Optical Transceiver Module — High-Density, Low-Power, Dual-Wavelength Design

1. 100G QSFP28 BIDI SR Product Overview

The 100G QSFP28 BIDI SR is a high-performance 100G QSFP28 Bi-Directional (BIDI) SR optical transceiver module designed for next-generation data centers and high-speed networking applications. This optical module supports both 100G and 40G Ethernet rates over multimode fiber, using dual-wavelength VCSEL technology (850nm/908nm) to enable bidirectional communication over a single fiber strand. Compliant with QSFP28 MSA and SFF-8636 standards, it offers hot-pluggability, digital diagnostics, and low power consumption.

2. 100G QSFP28 BIDI SR Key Features

  • Dual-wavelength VCSEL technology (850nm / 908nm) for bidirectional transmission
  • Supports 100G and 40G Ethernet with PAM4 and NRZ modulation
  • Hot-pluggable QSFP28 form factor
  • Digital diagnostic monitoring via I2C interface
  • Low power consumption: ≤ 4W
  • Operating case temperature: 0°C to 70°C
  • RoHS compliant and rugged metal housing

3. 100G QSFP28 BIDI SR Technology & Standards

This optical transceiver module complies with QSFP28 MSA, SFF-8636, and IEEE 802.3 standards. It utilizes PAM4 modulation for 100G operation and supports KP4 FEC. The dual-wavelength design allows full-duplex communication over a single OM3/OM4 fiber, reducing fiber infrastructure cost.

4. Working Principle

The module converts 4x25G electrical inputs into 2x50G optical signals using two wavelengths (850nm and 908nm). Each wavelength is transmitted and received simultaneously over the same fiber, enabling bidirectional data flow. Integrated DSP and CDR ensure signal integrity and low BER.

5. Applications

  • Data center interconnects
  • High-performance computing (HPC)
  • Cloud infrastructure
  • Enterprise networking
  • Telecommunication hubs

6. Specifications

7. Advantages

  • Reduces fiber count by 50% compared to traditional SR modules
  • Lower latency and power consumption than competitive models
  • Robust metal housing for improved thermal performance
  • Backward compatible with 40G networks

8. Service & Support

We offer a 5-year warranty, global shipping, and 24/7 technical support. Custom configuration and bulk pricing available. All optical transceiver modules are tested for compatibility with major OEM switches.

9. Frequently Asked Questions

Q: Is this module compatible with Cisco/Juniper/Arista switches?
A: Yes, it is compatible with most major brands that support QSFP28 MSA standards.

Q: What is the difference between SR and BIDI SR?
A: BIDI SR uses two wavelengths on one fiber, while standard SR uses separate fibers for Tx/Rx.

Q: Can it be used in 40G mode?
A: Yes, the module supports 40G mode via I2C configuration.

10. Precautions

  • Avoid bending fiber beyond minimum bend radius
  • Ensure clean fiber end-faces to prevent damage
  • Do not exceed maximum operating temperature
  • Use only with compatible MSA-compliant hosts
